SWING.

V SPECIFICATION forming part of Letters Patent N0. 780,871, dated anuary 24, 1905.

Application filed September 23, 1904. Serial No. 225,576..

To all whom it may concern;

Be it known that we, HUGH HOWELL DE FRANCE and CLAUDE OSCAR GARRIsoN, citi- Zens of the United States, and residents of Golden, in the county of Jefferson and State of Colorado, have invented a new and Improved Swing, of which the following is a full, clear,

' ward movement after the swing has passed a perpendicular line through the center of the carriage moves the carriage to the other end of the track, where it is again locked in a similar manner.

Reference is to be had to the accompanying drawings, forming a part of this specification, which represents a practical embodiment of our invention and in which similar characters of reference indicate corresponding parts in all the figures. 1

Figure 1 is a side elevation of a swing constructed in accordance with the principles of our invention. Fig. 2 is an end elevation thereof. Fig. 3 is a plan. Fig. 1 is an enlarged section on the line A A of Fig. 2, and Fig. 5 is a detail of the locking-plate. v

The swing comprises uprights 1, connected at the top by cross-pieces 2 and held in a vertical position by base-pieces 3 and braces 4:. To the cross-pieces 2 are securely fastened, by means of bolts 5 or equivalent securing means, the rails 6, which are formed with flanges 7, operating as tracks upon which the wheels of the carriage run. The rails 6 are further connected by cross-pieces, 8 at each end. Upon these cross-pieces are mounted locking-plates 9, which are slidable upon their securing means and are formed near the middle with locking-dogs 10. A hole 11 is made in each locking-plate for receiving a bolt 12, mounted on the carriage 13,, which supports out of position.

the swing. This bolt 12 is supported in a socket 14 and is normally pressed forward by a spring 15, located in, said socket and surrounding said bolt. One end of this spring 15 cooperates with a shoulder formed on the bolt 12 and the other end with the end of the socket 14. By this means the bolt is normally urged forward until a pin 16 in the end thereof strikes the socket 14:. The bolt 12 is in position on the carriage to pass into an opening 11, formed in each of lillGCIOSS-PIBCGS 8. Thls opening is in alinement with the opening 11 in the locking-plate 9 when said plate is in its highest position.

Upon the carriage 13 are mounted rods 17, on which are racks 18, which are normally held in position to engage the locking-dogs 10 by means of coiled springs 19, secured to the I the tracks 7 and support the carriage 13. In

each end of the carriage are supported two buffer-rods 21. These rods are supported in openings in the frame of the carriage l3 and are normally pressed forward by a bow-spring 22. The end of each buffer-rod has a head 23 formed thereon to prevent their passing completely through the frame, and thus getting The object of having the spring 22 is to cushion the blow which would follow if the carriage were suddenly arrested. The bow-spring 22 is made of such strength as to resist the maximum amount of force which would ordinarily be exerted upon it. Collars 23 on the rods 21 resist the pressure of the spring 22.

In order to provide for locking the carriage in different positions according to the amount of pulling force which urges it forward, the teeth are formed on the racks 18 so that the tooth which is nearest the locking-dog when the movement of the carriage has been completely arrested will hold it in substantially that position.

Suspended from the rods 17 are the supporting-pieces 24 for the swing. On two of these pieces is supported a seat of any'ordinary construction. The lower ends of the pieces 24 are connected, by means of arms 26, to keep them spaced at a uniform distance. The locking-plates 9 are formed with downward extensions 27, which are in the path of the pieces 24 and extend downward a suificient distance to be raised thereby when the swing reaches the heightintended for the unlocking to take place, as shown in dotted lines, Fig. 1.

The operation of the device is as follows: The swing is started with the carriage locked in position at one end of the track. hen the pieces 24: reach the height such that they will raise the plate 9 a sufficient distance to bring the opening 11 in the path of the bolt 12, said bolt will be pushed forward through said opening by the spring 15, which is in tension. At the same time the dog 10 will be lifted out of the rack 18, thus freeing the carriage. When the swing moves forward, the momentum produced thereby will move the carriage forward along the tracks until it reaches the I locking-plate 9.

opposite end. Here the bolt 12 at the opposite end of the carriage will pass through the opening 11 in the cross-piece 8 and strike the As the carriage moves farther the spring 15 will be compressed, thus setting the bolt for action as soon as the unlocking takes place. At the same time the rack 18 will ride over the dog 10 until the spring 22 has stopped the forward movement of the carriage by means of the buffers 21.

The spring 19 then draws the rack 18 upward, so as to cause the rack to engage the dog. By this means the carriage is automatically locked at the other end, and the same operation is continued from time to time.

While this is our preferred construction, we do not wish it limited to the precise details herein set forth, but only as defined by the claims.

Having thus described our invention, we claim as new and desire to secure by Letters Patent 1. The combination of a frame, a straight horizontal track supported upon said frame, a carriage adapted to run upon said track, and a swing supported entirely by said carriage.

2. The combination of a track, a carriage adapted to run upon said track, a swing supported by said carriage, and means for looking said carriage at one end of the track.
